The primary factor is the market value of your property. The County Auditor assesses your property according to market value not historical cost. Every six years your property will be re-appraised. The next reappraisal will be 2018 (payable in 2019) and the next triennial update will be 2015 (payable in 2016).

The second factor is the levies or additional taxes that the voters choose to pay in order to receive additional benefit or service.
